As uncomfortable and tedious as air travel can be, there are some airports in North America that fliers find to be rather pleasant. Bloomberg Businessweek recently completed a study outlining the most frustrating airports in the land, but it also created a list of the most satisfying for fliers.

Using a combination of data from a 39-question survey of 3,000 frequent fliers, on-time arrival and departure data, along with a calculation of how easy or difficult it is to reach the facility by car and public transportation, Bloomberg created what it called "The Airport Frustration Index." Measured out of a maximum of 100, airports with the highest frustration index are the most ... well, frustrating, while those with the lowest are the least.

With that in mind, here are the 15 least frustrating airports in North America.

1/

15. Charlotte Douglas International Airport (CLT)

Why it's pleasant: Charlotte's Douglas International Airport kicks off Bloomberg's list of the most satisfying airports, with a solid performance across the board. CLT finished 10th in commute time with an average of 34 minutes from downtown Charlotte to the airport. The facility also finished 11th in on-time performance, with 81% of its flights leaving within its departure slot.

2/

14. Boston Logan International Airport (BOS)

Why it's pleasant: With an average commute time of just 18 minutes from downtown Boston, Logan Airport is the easiest-to-reach facility featured in Bloomberg's 36-airport survey. In addition, Logan's 80% on-time rating is 12th best on the list. Survey respondents gave the airport's security setup, restrooms, and food/shopping facility solid but not spectacular, ratings.

13. Ronald Reagan Washington National Airport (DCA)

Why it's pleasant: According to survey respondents, Reagan National Airport has one of the best-managed check-in and security processes in North America. In fact, only Tampa, Portland, and Austin scored better. With an average trip of 32 minutes from the heart of D.C., DCA has the sixth-fastest commute. In addition, Reagan National also manages to get 80% of its flights out on time. The airport's only major weak point is its poorly rated dining and retail offerings.

Frustration Index: 44.8

Why it's pleasant: It's somewhat surprising to see Hartsfield-Jackson, an annual contender for the title of World's Busiest Airport, so high on our list. With easy access to and from the heart of Atlanta available via MARTA trains and several highways, ATL finished with the second-easiest commute at just 22 minutes.

The airport's 79% on-time percentage is good enough for 14th best. However that's very good considering its closest rival in terms of passenger volume, Chicago O'Hare, languishes in 35th place, with only 69% of flights leaving on time. Like a few of the other airports on this list, Hartsfield-Jackson did not exhibit any glaring weaknesses, but its amenities also didn't manage to wow many passengers.

5/

11. Detroit Metropolitan Wayne County International Airport (DTW)

Why it's pleasant: With 83% of flights departing on time, Detroit Metro Airport has the fifth-best on-time numbers. Survey reviewers gave the airport's check-in and security setup some of the highest ratings in the study. Fliers have also given DTW's bathrooms some impressively high marks.

6/

10. San Diego International Airport Lindbergh Field (SAN)

Why it's pleasant: San Diego International brings us into the top 10 of Bloomberg's list of least frustrating airports. The small, single-runway facility manages to get 77% of its flights out on time and can be reached via car or public transit from downtown San Diego in 38 minutes. San Diego's security lines and bathrooms scored well. However, the ratings for its food and retail offerings were less positive.

7/

9. Minneapolis-St. Paul International Airport (MSP)

Why it's pleasant: Minneapolis-St. Paul International was a longtime hub for Northwest (Delta) Airlines. MSP manages to get 82% of its flights out on time — good enough for sixth place on the list. Respondents also gave the airport's dining and retail offerings some of the highest marks in the survey.

8/

8. Ottawa International Airport (YOW)

Why it's pleasant: Serving Canada's capital, Ottawa International racked up some of the highest ratings in the survey for its security lines and bathrooms. The airport also has the best on-time percentage — 85% — of the 36 major facilities included in the survey. On the downside, the 60-minute commute from the city center to the airport is one of the longest on the list, and its food and shopping garnered some of the lowest ratings in the survey.

7. Seattle-Tacoma International Airport (SEA)

Frustration Index: 31.7

Why it's pleasant: SeaTac is the first of Pacific Northwest airports to appear on the list. A major hub for Alaska Airlines and Delta's new gateway to the Pacific rim, the airport is now become one of the busiest in the region. The airport manages to get a fantastic 83% of its flights off on time. Reviewers also found SeaTac's facilities to be solid.

10/

6. Tampa International Airport (TPA)

Why it's pleasant: Survey respondents absolutely loved Tampa International. The airport finished with the highest-rated security lines and bathrooms along with the second-highest-rated food and retail offerings. Keeping Tampa from reaching the top of the list was its 19th-ranked on-time performance: only 77% of flights take to air on schedule.

11/

5. Phoenix Sky Harbor International Airport (PHX)

Why it's pleasant: Phoenix Sky Harbor Airport made the top five with a solid overall performance. The airport managed to get 79% of its flights out on time and is located just 34 minutes away from the heart of Phoenix by car or public transit.

12/

4. Calgary International Airport (YYC)

Why it's pleasant: Calgary International makes it into the fourth spot on Bloomberg's list based on high survey ratings for its security lines and bathrooms. The airport's 82% on-time rating is good enough for eighth-best out of the 36 airports featured.

13/

3. Austin-Bergstrom International Airport (AUS)

Why it's pleasant: Austin-Bergstrom International's impressive finish comes on the back of its highly touted amenities. In fact, its security lines and bathrooms both finished as the third-highest rated on the survey. Its restaurants also garnered praise from respondents. Austin also finished as the 13th-easiest airport to access, but its 23rd-ranked on-time percentage prevented it from moving any further up the list.

14/

2. Portland Oregon International Airport (PDX)

Why it's pleasant:Portland International finished with the best airport amenities on the list. Its shops and restaurants finished with the highest ratings in the survey by a long shot, while its bathrooms and security lines finished second to Tampa. Portland also managed to get 82% of its flights out on time.

15/

1. Vancouver International Airport (YVR)

Why it's pleasant: Vancouver is once again the highest-rated airport in North America. Although the amenities at YVR are not as highly rated as Portland's, they're still very impressive. At 85%, Vancouver is tied with Ottawa and Montreal for the best on-time percentage.
